HOISTINGrMACHINE.

To (ZZZ 10720711 it may concern:

Be it known that. I, ALBERT J. VE'L'VIUK, a citizen of the United States, residing at Foley, in the county of Benton and State of hlinnesota have invented a new and useful Hoisting-Machine, of which the following is a specification.

My invention relates to improvements in hoisting machines, and the objects are to provide a hoisting machine with a certain novel friction gearing, so arranged that the machine may be fast and conveniently operated and hoisting done with less personal attention and aid than in the use of machines heretofore constructed.

In the accompanying drawing, Figure l is a side elevation of my hoisting device.

2 is an end elevation of the hoisting device shown in operation for hoisting hay into a barn, the latter is therefore shown on small scale near the machine.

Referring to the drawing by reference numerals, 1 designates a bed-plate upon which is mounted on a support 2 a gasolene engine, of which 3 is the cylinder, 41- the flywheels, 5 the shaft and 6 a pulley having flanges 7 by which to retain in place a belt 8 when the latter is idle and slack, as will presently be fully described. Mounted on the same base, 1, or adjacent the engine, are two frames, 9 9", each of which is provided with a vertical gap 10, in which slides a bearing block 11, which by means of a link 12 is connected with a crank-shaft 14, to which is fixed a hand-lever 13, which may be sprung into either one of the notches 15, 15 and 16 in a keeper 17 fixed on the frame. Journaled in said blocks 11 are the ends of two cable drums, 18 and 19, of which the former is provided with a belt pulley 20 and the latter with a friction pulley 21 slightly spaced from the belt pulley and adapted to be driven only when in frictional contact with the pulley 6 on the engine shaft. Attached to and partly wound upon the drum 18 is a cable 22, and likewise attached to the drum 19 is a. lighter cable '23, which is wound in the opposite direction to that in which the cable 22 is wound.

The operation of the machine is illustrated in Fig. 2, where 9.4: designates a barn shown in vertical sect-ion, 25 is the door opening through which hay is to be deposited into the barn. For said purpose the usual rail 26 is secured by hangers 27 underneath the Specification of Letters Patent.

roof 28 of the barn; a carriage 29 is mounted on the rail, a sheave 30 is mounted in the rear end of the barn, the cable 22 is passed over guide sheaves 3 8'2, 33, 3 1, 30 and a sheave on the carriage, and after being passed underneath a sheave 36 on the hay carrier 37 it is secured at 38 to the carriage The cable 2?; attached to a trip lever 39 of the haycarrier or holder 37. Said holder or carrier may be a hay-sling, or a fork, or any device which will hold the hay while it is lifted from the supply in front of the barn and raised to and moved into the door near the top of the barn and to its destination in the barn. Such devices are of various constructions but each of them is provided with a trip which when pulled by a rope will cause the device to dump its load and be ready for a new load. Now, if the device 37 has been charged or filled with hay and the engine is running and the lever 13 is thrown to the position shown, the pulley 6, belt 8 and pulley 2O rotate the drum 18 and cause the device 37 to rise up to the carriag'e 29, and by continuing the pull on cable 22 the carriage will be moved upon the rail into the barn; when the desired place is reached the lever 13 is thrown into the notch 16, and as this causes the links 12 to lift the blocks 11, the belt 8 is put out of commission by becoming slack, and the friction pulley 9.1 is forced against the engine pulley 6 which will then rotate the upper drum 19; this causes the cable, or rope, 23 to trip the hay carrier, and thereafter pull it and the carriage 29 back to the guard 10 at the outer end of the rail; further pulling on the rope 23 will also bring the hay-carrier down from the carriage to the supply of hay on a waggon or otherwise in front of the barn, where the device is filled and hoisted again by the cable 22. During the loading of the carrier both drums stand still, the lever 13 being placed in the notch 15*. It will also be understood that the winding of either cable upon its drum causes the other cable to unwind from the other drum to the extent such unwinding may be necessary;

From the description given it will be underst-ood that if manual help is scarce or expensive. the same person hauling the hay to the barn may operate this hoisting machine, load the carrier 37 and deposit the hay at any desired place in the barn. And that similar economy is possible in using the machine for unloading and storing stone, gravel, sand, potatoes, wheat and any other materials ormatter for which the machine may be employed.

What I claim is 1. T he combination with a suitable framework and journal bearings therein, of a driving shaft and two driven shafts arranged substantially in the same plane, a pulley fixed on each shaft, a belt passed over the driving pulley and over the driven pulley farthest away from the driving shaft; the third and intermediate pulley being small enough not to contact with the belt, a cable drum fixed on each of the driven shafts; the journals of the driven shafts being movable toward and away from the driving shaft, and means by which the operator may readily move said journal bearings and thereby cause the driving pulley to operate alternately the intermediate pulley by friction or the other driven pulley by the belt.

2. The combination with the shaft of a mo tor, of apulley fixed on the shaft, two other shafts arranged parallel to and at different distances from the motor shaft, a belt pulley fixed on the shaft farthest away from the motor shaft, a friction pulley fixed on the intermediate shaft, a belt straddling the intermediate pulley and engaging the two other pulleys, and means for moving the two shafts toward and away from the motor shaft.

In testimony whereof I aflix my signature,

in presence of two witnesses.
